Heart Valve Disease

Valvular Heart Disease is the third most common cause of heart problems in the United States.

There are four cardiac valves that direct blood flow forward through the four chambers of the heart. Heart valve disease can occur with any one or with a combination of the valves, and may lead to heart failure or even sudden death if left untreated. 

Diseases of the mitral and aortic valves (the valves on the left side of the heart) are most common, affecting over 5 percent of the general population.

Heart valve disease implies that a valve either fails to open properly (“stenosis”) or fails to close properly, allowing backward flow of blood (“regurgitation”).

Heart Valve Disease Care Team

Daniel J. Waters, D.O., Cardiovascular Surgeon

Dr. Waters is Board Certified in General Surgery and Cardiovascular & Thoracic Surgery, is a Past-President of the Iowa Society of Thoracic Surgeons, and is a Fellow in the American College of Cardiology.  He has practiced in Mason City for more than 20 years.

Byron Beasley, M.D., Cardiologist

Dr. Beasley trained at the University of Iowa, is Board Certified in Internal Medicine, and is a Fellow in the American College of Cardiology.  He is an expert in Echocardiography, a sound wave test, which is often used to diagnose heart valve problems.  Dr. Beasley has been a cardiologist in Mason City for more than 30 years.

Kristi Wood, R.N., Care Coordinator

Kristi will stay in direct contact with valve patients to provide support and to assist them in efficiently navigating through the health system from diagnosis and treatment to follow-up.  She has experience in caring for cardiac patients and, as a Cardiovascular Recovery Unit nurse for many years, knows first-hand the importance of coordinated care.

It is a priority among all the cardiac physicians at Mercy Heart Center to provide the best services available to diagnose, treat and, when necessary, surgically correct valve problems.

Certain types of valve problems, like aortic stenosis, can be associated with poor survival, so early identification, diagnosis and appropriately timed treatment are very important.
